I'm sorry to hear that you're experiencing pimples on your back and face. This condition is commonly known as acne, which can be caused by factors like excess oil production, clogged pores, bacteria, or inflammation.

Here are some general suggestions to help manage acne:

• Keep the skin clean: Gently wash the affected areas twice daily with a mild cleanser.
• Avoid harsh scrubbing: This can irritate the skin and worsen pimples.
• Use non-comedogenic products: Choose skincare and body products that do not clog pores.
• Avoid picking or squeezing pimples: This can lead to scarring or infection.
• Wear loose-fitting clothing: This helps reduce irritation on your back.

Since acne can vary in severity and may sometimes require medical treatment, it is important to consult a dermatologist. They can evaluate your skin condition and recommend appropriate treatments, which may include topical or oral medications.

If you are currently taking any medications or have other health concerns, please share this information with your dermatologist to ensure safe and effective care. If your pimples are painful, spreading, or accompanied by other symptoms, seek medical advice promptly.To narrow down potential causes, we will need some more information.Please tell me your age and gender.
